When the top-tier everything-smartphones cost between $200 and $300, I can't blame you for dubiously eying a $50 phone. However, if your budget is top of mind, and Android is where your heart lies, then do yourself a favor and check out the Pantech Burst.
Why? It has 4G LTE, a 4-inch Super AMOLED screen, a (good) 5-megapixel camera, a front-facing camera, and a 1.5GHz dual-core processor. Poorer call quality and battery life are the price trade-offs, but if you can live with that, you'll find in the Burst a Gingerbread device that pretty much does it all.
